The Friction plug welding (FPW), is a kind of process to join the two dissimilar/similar materials and no external heat is applied or no molten state involved. As no melting occurs, friction welding is not a kind of fusion welding process, but more than a counterfeit welding technique. The joint efficiency may be increased by interpolating heat source or pre-heating at the workpiece surface. The generation of heat flux at the mean surface is calculated by friction during the materials to consider the friction co-efficient. By changing the diameter of the plug, the land width can be changed to get an impact on the temperature profile. Mathematical and Analytical modeling has computed the impact of pre-heating. The temperature distribution values during the workpiece were computed for various plug diameters with various pre-heating temperature values from 250ºC-550ºC.
